It’s been difficult to find info on this boat however since it was made in the 80s. The rigging that it came with is a simple 2 pulley system with one being connected to the end of the boom and the other to a fixed bar on the aft. I can’t find other boats that are rigged in this manner so I’m not sure if it’s ok. The pulley is only 1 rope wide so the main sheet just kinda hangs loose in it.

You're talking about the mainsheet? How about a photo and we should be able to sort you out?
